cement raw mill


Posted on November 19, 2018



Rawmill - WikipediaA rawmill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The rawmilling stage of the process effectively defines the chemistry (and therefore physical.cement raw mill,Cement- and Raw Mill - A TEC - Innovative Technologies for Tailor .Whether ball mill or vertical roller mill (VRM), A TEC offers the expert solution for efficiency optimization to increase mill productivity and/or reduce mill power.
